Abstract: A method of controlling pulse width modulation (PWM) applied to at least one power inverter to generate a weld current for cutting or welding comprises: receiving current values indicative of the weld current during a cycle of the PWM; receiving a target current value indicative of a target current for the weld current; during the cycle, turning ON a pulse to energize the at least one power inverter; and after turning ON the pulse, repeating multiple times during the cycle: determining whether to adjust an on-time of the pulse based on the current values and the target current value in order to drive the weld current toward the target current; and adjusting the on-time responsive to determining.

Abstract: An article for use as a negotiable instrument includes a substrate having a front side and reverse side; first machine-printed information on the substrate's front side including an account number associated with the negotiable instrument, and a unique identifier associated with the negotiable instrument, the first machine-printed information uniquely identifying the negotiable instrument; and second machine-printed information on the substrate's reverse side that corresponds to the first machine-printed information such that comparison of respective images of the substrate's front and reverse sides indicates that the images correspond to the same negotiable instrument.
